iAP "Missing Metadata" instead of "Waiting for Screnshoot"

Hi, I want to test my in app purchases with my developer app but I can't get the IAP to work in iTunes connect.

I have filled out any field but didn't uploaded the screnshoot for the iAP but the status does not change from Missing Metadata to Waiting for Screenshoot.

The "Waiting for Screenshoot" seems to be mandatory for testing iAP in sandbox mode as it is described here: https://developer.apple.com/library/content/technotes/tn2259/_index.html
